Is Bitdefender GravityZone legit? What the audits, tests, and reviews show

Who owns Bitdefender

Bitdefender grew out of SOFTWIN, a Romanian software firm, and took its current name in 2001. Founder Florin Talpeș is CEO and the main shareholder. In 2017 the London private equity firm Vitruvian Partners bought a 30% stake, which valued the company at more than $600 million. It reported €330 million in revenue for 2024 and has more than 2,000 staff (Wikipedia).

It has bought three security firms in recent years: Horangi Cyber Security in Singapore (2023), the BitShield division (February 2025), and Mesh Security, an email security company (2025). Bitdefender also licenses its detection engine to other security vendors, and it says more than 150 technology brands use it.

The audits Bitdefender publishes

Its certifications page lists a SOC 2 Type 2 report covering security, availability, and confidentiality for November 16, 2024 to November 15, 2025, an annual HIPAA Security Rule audit, and ISO 27001, 27017 (cloud security), 27018 (personal data in the cloud), and 9001 certificates dated 2026. The first page of each report is public; the full SOC 2 report is available on request, which is standard practice.

For a buyer, the SOC 2 report is the one to request. It covers the GravityZone cloud service your endpoint data flows through, and a security questionnaire from your own customers or insurer will usually ask for it.

How GravityZone does in independent tests

Test labs are the best outside check on whether security software works, and GravityZone's record there is strong. AV-Comparatives runs a Business Security Test twice a year. Across the six reports from 2023 to 2025, 2,901 real-world attack cases in total, GravityZone was compromised 3 times. CrowdStrike Falcon Pro was compromised 28 times and Microsoft Defender 29 times in the same tests.

In AV-Comparatives' 2026 Endpoint Prevention and Response test, Bitdefender was one of 11 certified products out of 14. It scored 99.7% on prevention and response across 50 attack scenarios, level with VIPRE and behind only Elastic (100%). Its five-year cost per agent ($225) was the third lowest. AV-TEST gave Bitdefender Business Security its Best Protection 2025 award for corporate users. In MITRE's 2024 managed services evaluation, Bitdefender sent 82 alerts, the fewest of the 11 participants.

Labs test configured products under controlled conditions. They tell you the engine is good. They don't tell you how quickly support answers or how long setup takes, and that is where the complaints are.

Security incidents worth knowing

On March 20, 2010, a faulty Bitdefender update classified every program and DLL file as infected on computers running 64-bit Windows. It is the incident people still bring up.

In April 2025, Bitdefender disclosed three vulnerabilities in the GravityZone console and update server (CVE-2025-2243, CVE-2025-2244, and CVE-2025-2245). The worst, rated 9.5, let an attacker run commands on the console host. Console version 6.41.2-1 fixed them (Heise). If you run the on-premises console, check that it is on 6.41.2-1 or later.

What GravityZone users complain about

We publish every critical review we collect. Across the 3 platforms on this site, three complaints repeat: support is slow to answer, the console has a learning curve, and the agent can weigh on older PCs and Macs. Small businesses without IT staff are the most frustrated.

Plan for setup time, or buy through a partner or managed service provider who will run it for you. Read the critical reviews before you decide.

Refunds and renewals

Online business purchases come with a 30-day money-back guarantee on first orders. Subscriptions renew automatically unless you turn renewal off in your billing profile, and Bitdefender accepts refund requests up to 30 days after a renewal charge. Our refund and cancellation guide covers the steps.
